The last one of these exploded, so I had high hopes of excitement when I ordered several with the intention of doing an experiment to change the colour of the LEDs in different units and see which one attracted the most bugs. Rather annoyingly, these units have surface mount LEDs in them. This makes it a bit trickier to fit my intended straw hat LEDs.
But it gets even more interesting with a very different and much better designed PCB inside with what appear to be properly rated components.
Note that the grid in these units is easy for kids to touch and is referenced to the mains supply (wall power), so definitely not for use where a kid could reach it. Also note that the unit holds a charge for a very long time when unplugged, as it has no discharge resistor for the main X2 470nF cap charged to 660V.
